使用步骤：

1. 引入maven依赖文件
   Importing maven dependency files.

       <dependency>
           <groupId>io.github.darmi7</groupId>
           <artifactId>mongo-lambda-query</artifactId>
           <version>1.3.0</version>
       </dependency>
   

2. 开启插件注解，加上需要扫描mongo实体的包路径
   Open plug-in annotations, plus the package path that requires scanning mongo entities.

   @EnableMongoLambdaQuery
   @EnableMongoRepositories(basePackages = "com.darmi.demo.repository.mongo")
   public class Application
   

3. 编写查询代码
   Write query code

       @Repository
       public interface TaskRepository extends MongoRepository<Task, String> {
   
           default Task one(TaskCriteria taskCriteria) {
               return MongoLambdaQuery.lambdaQuery(Task.class)
                   .is(Task::getName, taskCriteria.getName())
                   .one();
           }
           
           default List<Task> list(TaskCriteria taskCriteria) {
               return MongoLambdaQuery.lambdaQuery(Task.class)
                   .gt(Task::getCreated, taskCriteria.getBegin())
                   .lt(Task::getCreated, taskCriteria.getEnd())
                   .list();
           }
           
           
           default Page<Task> search(TaskCriteria taskCriteria) {
               return MongoLambdaQuery.lambdaQuery(Task.class)
                       .is(Task::getName, taskCriteria.getName())
                       .is(Task::getType, taskCriteria.getFuzzyName())
                       .reg(Task::getName, taskCriteria.getName())
                       .gt(Task::getPoints, taskCriteria.getPoints())
                       .gt(Task::getCreated, taskCriteria.getBegin())
                       .lt(Task::getCreated, taskCriteria.getEnd())
                       .page(taskCriteria.getPagination());
           }
       }
